Hauv kev lag luam xws li lub zog tauj dua tshiab, kev xa hluav taws xob, roj teeb cia, thiab cov tshuab photovoltaic,diffusion vuam tshuabua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom sib txuas yooj yim, lub hwj chim busbars, cov khoom siv hluav taws xob sib xyaw, thiab cov khoom siv hluav taws xob muaj kev ntseeg siab siab -.
Ntawm tag nrho cov txheej txheem tsis muaj, vuam kub thiab vuam siab yog ob qho tseem ceeb tshaj plaws uas txiav txim siab kev sib koom ua ke, lub zog siv tshuab, thiab kev ntseeg ntev ntev -.
Kev tswj kom zoo ntawm cov kev txwv no cuam tshuam ncaj qha rau cov khoom lag luam thiab tseem cuam tshuam li cas cov neeg siv yuav tsum ntsuas thiab xaiv cov khoom siv vuam diffusion.
Phau ntawv qhia no piav qhia txog qhov kub thiab txias, lawv ua haujlwm ua ke li cas, thiab yuav tsum tau txiav txim siab li cas thaum kawm txog diffusion vuam lossis xaiv lub tshuab tsim nyog rau kev tsim khoom.
Vim li cas Kub thiab Siab Teebmeem hauv Diffusion Vuam
Diffusion welding yog ib qho khoom siv - lub xeev cov txheej txheem. Tsis zoo li fusion vuam, cov ntaub ntawv tsis yaj. Hloov chaw, qhov sib koom ua ke yog tsim los ntawm atomic diffusion ntawm qhov kub thiab txias thiab tswj tau siab.
Cov txheej txheem kev sib txuas yog nyob ntawm:
- Yas deformation ntawm qhov chaw sib cuag
- Ua kom muaj kev sib cuag tiag tiag ntawm cov khoom siv
- Atomic migration hla lub interface
- Tsim kom muaj kev ruaj khov metallurgical daim ntawv cog lus
- Tshem tawm cov voids thiab nto oxides
Vim tias tsis muaj melting tshwm sim, weld zoo nyob ntawm:
- Qhov kub txaus los ua kom muaj atomic diffusion
- Txaus siab los tsim intimate nto kev sib cuag
Qhov no yog vim li cas diffusion vuam tshuab yuav tsum tau tswj qhov kub thiab txias thiab ruaj khov siab tswj tshuab, tsis yog lub zog tso zis ntau.
Hom Welding Temperature Ranges
Txoj Cai Kub Kub: 0.6-0.8 ntawm Melting Point
Hauv kev xyaum ua lag luam, diffusion vuam kub feem ntau yog tswj ntawm60% -80% ntawm cov khoom siv melting kub (Tm).
Qhov ntau no tso cai rau cov atomic diffusion zoo yam tsis ua kom yaj lossis kev puas tsuaj.
Common Industrial Temperature Ranges
| Khoom siv | Melting Point (zeeg) | Diffusion vuam ntau yam (degree) |
Tej kev siv |

| Copper-Stainless hlau | -- | 750–900 | Dissimilar hlau pob qij txha |
Nyob rau hauv cov cheeb tsam no, diffusion welding tuaj yeem ua tiav kev sib koom ua ke txog li 90% lossis ntau dua ntawm cov khoom siv lub zog, nrog rau cov khoom siv hluav taws xob zoo thiab kev ruaj ntseg.
Kev tswj qhov kub thiab txias hauv kev siv hluav taws xob thiab khaws cia
Hauv kev tsim khoom tiag tiag, ntau -theem cua sov profiles tau dav siv:
- Preheating theem - txo cov kev ntxhov siab sab hauv
- Lub ntsiab cua sov theem - activates atomic diffusion
- Tuav theem - stabilizes diffusion txheej txheem
- Tswj cua txias theem - tiv thaiv cov kab nrib pleb thiab kev puas tsuaj
Piv txwv li, nyob rau hauv tooj liab-aluminium composite busbar vuam:
- Maj mam cua sov los ntawm chav sov mus rau 300℃→ 500℃→ 600 degree
- Qhov no tiv thaiv thermal kev nyuaj siab tshwm sim los ntawm txawv expansion tus nqi
- Ua kom ruaj khov kev sib raug zoo thiab kev ua haujlwm ruaj khov
Qhov no yog vim li cas siab - zoo diffusion vuam tshuab yuav tsum txhawb programmable kub nkhaus thiab ruaj khov thermal tswj, tsis yog qhov kub siab tshaj plaws xwb.
Hom Vuam Siab Ntau Yam
